By 1949 Petry was already an established writer of adult fiction, but
The Drugstore Cat, which was published the same year she became a mother, was her first attempt at children's literature. Unlike her previous books, the story doesn't explicitly discuss
race and racism, The story was also unique for its contemporary setting; her three subsequent children's books would all be historical. There is an autobiographical aspect to the story. Petry's father was the first African American to pass the Connecticut pharmaceutical exam, and her aunt was one of the first African American women to pass the exam. In 1988,
The Drugstore Cat was reissued by
Beacon Press, under its Night Lights imprint. ==Reception==
